For modded Xbox 360s, the XBLA version of Marvel vs. Capcom 2

• Color Edit Mode: Unlock palettes that were previously only available via Action Replay on Dreamcast.
• Balance Patches: Want to nerp Storm’s hailstorm or remove Magneto's magnetism? There are XEX patches for that.
• Character Swaps: Play as Shadow Lady or Roll’s alternate version directly on the character select screen without button codes.

All Characters Unlocked: You get the full 56-character roster from the start.

Recommendation:
Use the XBLA version (approx. 200–300 MB) over FBA or MAME emulators on RGH – it’s faster, more stable, and has proper button mapping for arcade sticks.
